FEEDING DEVICE FOR PLANlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 401,524, dated April 16, 1889. Application filed November 2'7, 1388- Serial No. 291,961. (No model.)

To allwhom it may concer'w Be it known that we, JAMES F. \VELQH, of Brooklyn, (Green Point,) in the county of Kings and State of New York, and ERNST F. AUTEN- RIETH, of New York, in the county and State of New York, have invented a new and useful Improvement in Feeding Devices for Planing- Machines, of which the following is a specification.

\Ve will describe in detail portions of a planingmachine embodying our improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure l. is a plan or top View of a planing-machine embodying our improvement. Fig. 2 is a longitudinal section taken on the line 41;, Fig. 1. Fig. 3 is a vertical section taken on the line 2 y, Fig. 1. Fig. at is a detailed vertical section taken on the line 2 ,2, Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

\Ve have only illustrated such parts of a planing-machine as are essential to an understanding of our invention. In these, A designates the frame of the machine.

B designates a shaft upon which is a pulley, a, by which motion is transmit-ted to the shaft. This shaft is j ournalcd in suitable bearings in the frame A, and has formed upon it at intervals throughout its length worms (1. These worms gear with worm-wheels a mounted upon the lower end of upright shafts or spindles of, journaled in suitable hearings in horizontall y-extending portions a of the frame. Up on the ends of the shafts or spindles (0 are mounted vertically-extending presser-rollers a. When the shaft B is rotated, rotary motion is imparted to the rollers 0;, whereby a board passing between them will be guided and its forward movement will be assisted. \Ve have shown this machine organized to feed forward a number of boards at a time. For this reason we have shown three pairs of the presserrollers a, the rollers being arranged in two rows. Near the other end of the shaft B there is mounted upon it a sprocket-wheel, b. A sprocket-ehain, l), transmits motion from the sprocket-wheel Z) to a sprocket-wheel, 11 mounted upon a horizontally-extend in g shaft,

1). Upon the shaft 1) are rigidly secured a number of rotary disks b". \Ve have shown but three of such disks, but we may use any desired number, according to the number of boards which it is desired to pass through the machine. The rotation of these disks operates to feed a board forward by its frictional contact with the board. Upon the shaft 1) there is also mounted a sprocket-wheel, b, from which motion is transmitted by means of a sprocket-chain, Z), to a sprocket-wheel, b mounted upon a horizontal]y-extending shaft, 12 Upon the shaft 19 are rigidly mounted rotary disks b". The disks b are in line with the disks l) and the shafts b and b and consequently all of the disks rotate in unison.

\Ye desire to place a number of boards together to be successively fed forward, and which will be successively brought into contact with the rotary feeding disks b Z1. \Ve have shown three boards adapted to be successively brought into cont-act with each of the disks b b. Each of the sets of three boards, having been placed upon the shafts 5 11 is moved forward until the two boards farthest from the adjacent feed-disks b b" abut against a stop, b The steps b are mounted upon a horizoi[tally-extending shaft, I), arranged. between the presser-rollers and the feed-disks b In Fig. 4 it is shown more clearly that the shaft Z) at intervals throughout its length is screw-threaded. These screw-threads engage nuts 1), extending downwardly from the stops b By rotating the shaft 1), as shown, by means of a hand-wheel, I), the stops b may be moved horizontallyin unison. This is for the purpose of accommodating boards of different widths. The stops are maintained in a vertical position by means of a rectangularly-shaped bar, 7/, extending between the side portions of the frame and through suit able apertures in the stops, so that the stops may slide upon the bar.

It will be seen that but one board is in contact with each of the feed-disks l) b at a time. I The other boards of each set are maintained firmly against the one in contact with the feeddisks, and the latter firmly against the said disks by m cans of yielding pressers D. These yielding pressers are here shown as fingers mounted near their rear ends upon up wardlyextending pins or studs d, which latter extend upwardly from a cross bar or plate,D. The pressers D are vertically adjustable on the pins or studs (Z, and are maintained in any position into which they may be adjusted by set-screws d. The pins or studs (Z extend loosely through apertures in the cross bar or plate D, and are free to turn therein. Upon their lower ends in the example of improvement shown are rigidly mounted horizontallyextending arms, (1 which are below the cross bar or plate D. The arms (1 together with collars d on the pins or studs (,1 above the cross bar or plate D, prevent vertical displacement of the pins or studs.

Secured to the outer ends of the arms (1 are cords or chains d', which cords or chains extend for a distance horizontally and then pass over pulleys d, mounted upon pins or studs (1, extending from the cross bar or plate D. S uspended by the cords or chains (l are weights d These weights operate to so rock the pins or studs (Z as to cause the pressers D to press firmly, and yet with a sliding pressure, against the outer board of the set. Of course, instead of using weights to effect this operation of the pressers, springs might be employed or the pressers themselves might be made resilicnt.

A nzachine having been set in mo i m, the board of each set in contact with the feedingdisks 19 is fed forward by said disks and. between the presser-rollers the other boards of the set being maintained against forward movement by the stops b \Vh en the boards next the feedingdisks have been fed past them and the presser-rollers have drawn the same past the stops Z1 the pressersD operate to force other boards quickly and firmly into contact with the feeding-disks b h It will therefore be seen that a large number of boards may be placed in the machine at one time, and that the same will be automatically set forward one after another.

It will be seen that all the feeding-disks rorate in vertical planes and have their faces contacting with the board to drive it. It will also be seen that the yielding pressers are independent of the feeding-disks.

lVhat we claim as onr invention, and desire to secure by Letters Patent, is-

1. In a planing-machine, the combination, with rotary shafts, of feeding-disks mounted on said shafts so as to rotate in vertical planes and having their faces contacting with the board to be fed, and yielding pressers independent of said disks operating to force the board into contact with the disks, substantially as specified.

2. In a planing-machine, the combination, with rotary shafts, of feeding-disks mounted on said shafts so as to rotate in vertical planes and having their faces contacting with the board to be fed, yielding pressers adapted to maintain a number-of boards in contact with each other and one of said boards in contact with the feeding-disks, and a stop for preventing a forward movement of any of the boards except the one in contact with the feeding-disks, substantially as specified.
